Description of the invention The invention relates to a catalyst composition and its use in a hydroconversion process. 'A hydrocarbon oil containing aromatic compounds in the process is based on This catalyst composition is contacted with hydrogen in the presence. One method for preparing the catalyst composition also forms part of the uninvented. Hydrotreating catalysts are well known in the art. Conventional hydrotreating catalysts include at least one Group VIII metal component and / or at least an ethnic vIB metal component supported on a refractory oxide support. The Group VIII metal component may be based on a non-rhenium metal such as nickel (Ni) and / or europium (co), or may be based on a precious metal such as platinum (pt) and / or palladium. The VIB metal composition includes mainly molybdenum (Mo) and tungsten (W). The most commonly used refractory oxide support materials are inorganic oxides such as silica, alumina, and silica-alumina and aluminosilicates, such as modified zeolite gamma. Specific examples of conventional hydroprocessing catalysts are NiMo / alumina, CoMo / alumina 'NiW / silica-alumina, Pt / silica-alumina, PtPd / silica-alumina, P t / modified Zeolite γ and PtPd / modified zeolite γ. Hydrotreating catalysts are generally used in processes in which a hydrocarbon oil feed is contacted with hydrogen to reduce its aromatic, sulfur, and / or nitrogen content. In general, the hydroprocessing method in which the reduction of aromatic hydrocarbon content is the main purpose is called a hydrogenation method, and the method mainly focused on reducing the sulfur and / or nitrogen content is called hydrodesulfurization and hydrodenitrogenation, respectively method. Current environmental standards require very low aromatic hydrocarbon content and sulfur and nitrogen content of petroleum products and it is generally expected that the specifications of aromatic hydrocarbons, sulfur and nitrogen will become more stringent in the future. Thus, in the refining of hydrocarbon oil fractions, the ability to strongly hydrogenate, strongly hydrodesulfurize, and strongly hydrodegas will become increasingly important.

Printed by the agency 464687 A7 _______ B7 V. Description of the invention #) The effective hydrogenation of monoaromatic compounds is usually difficult to use. The hydrotreating catalyst was achieved. On the other hand, conventional, dedicated aromatic hydrocarbon hydrogenation catalysts often have relatively low allowable amounts of sulfur and / or nitrogen to make them appear poor in the presence of a substantial amount of sulfur and / or nitrogen-containing compounds. Its hydrogenation activity. For this reason, the conventional method for reducing the amount of aromatic hydrocarbons and sulfur- and nitrogen-containing compounds is a two-stage process, which has a first hydrodesulfurization and / or hydrodenitrogenation stage and is usually removed After the generated hydrogen sulfide and ammonia, it is used for the second stage of hydrogenation of the aromatic hydrocarbons that remain. The present invention is directed to provide a hydrotreating catalyst which exhibits excellent hydrogenation activity of aromatic hydrocarbons, and at the same time has excellent hydrodesulfurization and / or hydrodenitrogenation activity. Thus, this means that the catalyst composition should be able to effectively promote the hydrogenation of aromatic hydrocarbons in the presence of substantial amounts of sulfur- and nitrogen-containing compounds. The present invention is further directed to providing a hydrotreating catalyst which exhibits excellent hydrogenation activity against mononuclear aromatic hydrocarbons. It will be appreciated that the use of such catalysts in hydroprocessing methods provides one more potential to meet future low content specifications for (mononuclear) aromatic hydrocarbons, sulfur and nitrogen. Thus, in the first aspect, the present invention relates to a kind comprising one or more precious metals selected from platinum, palladium and iridium, and containing 0.1 to 15% by weight, supported on an acidic support, and the weight A catalyst composition of 2 to 40% of manganese and / or rhenium, the weight percentage indicates the amount of metal based on the total weight of the support. Manganese and chains belong to the family of the periodic table ViIB. The third race VnB metal 'diet' is not qualitative due to its lack of quality.

Description of the invention (3) Therefore, it is a useless metal with catalytic activity, that is, platinum and / or succinate on the one hand and / or sensitization on the other, and / or baht, on the other hand, can be in the form of an element, such as an oxidation A substance, such as a phosgene, or a mixture of two or more of these forms, is present. As will be discussed in detail later, a suitable preparation method used to prepare the catalyst includes the final stage of calcination in air, which will cause catalytically active metal systems to at least partially convert into their oxides. This final calcination stage will result in the conversion of substantially all catalytically active metals to their oxides. If the catalyst is subsequently contacted with a sulfur-containing feed, at least part of these oxides will be sulfided and thus converted into corresponding sulfides (" on-site " sulfidation). In this case, very good catalyst performance has been observed and it is therefore considered that the presence of catalytically active metals in the catalyst at least partly as sulfides is a preferred embodiment of the present invention. Thus, the catalyst can also be subjected to a separate presulfidation treatment before it comes into contact with the feed. The degree of sulfidation of metal oxides can be controlled by related parameters, such as temperature and partial pressure of hydrogen, hydrogen sulfide 'water and / or oxygen. Metal oxides can be completely converted into the corresponding sulfides', but an equilibrium state will be formed between the oxides of the catalytically active metals and the sulfides, so that the catalytically active metals such as oxides and such as sulfides Both exist. As will be discussed in more detail below, the catalyst according to the present invention can be suitably used in various hydroconversion processes. It has been found that such catalysts are used in gasification oils and thermally and / or catalytically cracked distillation oils (such as light cycle oils and cracked cycle oils) and mixtures of two or more of these oils; Department is particularly useful. These oils usually contain a relatively large amount of aromatic-6-sheet paper from CNS A4jm (2ί〇Χ297 / ^ ¾) (please read the precautions on the back first 71¾ this I) Printed by the Consumers 'Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs β 8 7 Α7----------------------- B7 V. Inventions ~~)' "-Compounds, sulfur-containing compounds and nitrogen-containing compounds. Due to environmental specifications, it is often necessary to reduce the number of these compounds. For reaching certain technical specifications, such as the sixteen burns in the case of alpha car gas oil, the smoke point in the case of jet fuel and the color and stability in the case of lubricating oil fraction, reduce Aromatic compounds are also desirable. When the catalyst according to the invention is used in the hydrotreatment of gas-generating oils (thermal and / or catalytic cracking equipment oils and mixtures of two or more of these oils), for example, automotive gas-generating oils The reduction in specification requirements can be achieved in a single stage. It has been found that the catalysts of the present invention are particularly active in reducing the amount of mononuclear aromatic hydrocarbons in the final product, even in the presence of substantial amounts of sulfur- and nitrogen-containing compounds. The catalyst according to the invention comprises from 0 to 5% by weight of platinum and / or from and / or iridium and from 2 to 40% by weight of manganese and / or rhenium as catalytically active metals. If a lower amount of catalytically active metal is used, the activity of the catalyst becomes too low to be commercially attractive. On the other hand, if the amount of the catalytically active metal is higher than the indicated upper limit, a further increase in catalytic activity will not result in the cost of another amount of metal. In particular, this applies to Ming and New Zealand. Good results can be obtained with catalysts containing 3 to by weight of precious metals (ie, starting and / or palladium and / or iridium) and 2 (preferably 5) to 30% by weight of manganese and / or baht. . Regarding the precious metal component ', it is preferable to use only a handle, and as for the chain, the chain is preferably a metal. Therefore, a very preferable catalyst is a catalyst containing palladium and a chain as a catalytically active metal. The carrier used to carry the catalytically active metal is an acidic carrier.

Description of invention (8) The printed materials produced by the Consumer Cooperatives of the Central Standards and Quarantine Bureau of the Ministry of Economic Affairs are produced by catalytically cracked gasoline and gasoline. Gas oil, light gas oil, thermal and / or catalytic cracking distillation oil (such as light cycle oil and cracking cycle oil) and a mixture of two or more of these oils. Many of these feeds usually include At least 70% of hydrocarbons boiling between 150 and 450 ° C. When used in this type of hydrogenation catalyst, it is preferred that the carrier contain a binder in the amount indicated above in the case of hydrotreating The preferred acidic material in the carrier is a zeolite γ that is the best modified salt zeolite. It has been found that the catalyst still shows excellent performance even in the presence of substantial amounts of sulfur and nitrogen-containing compounds. Its hydrotreating activity is particularly effective for hydrotreating mononuclear aromatic hydrocarbons. In addition, The catalyst is also very effective for the hydrogenation of dinuclear aromatic hydrocarbons and higher aromatic hydrocarbons (two or more polynuclear aromatic hydrocarbons). The present invention also relates to a method for preparing the above-mentioned catalyst, the method comprising Catalysis or ion exchange technology, followed by drying and scorching, and pre-sulfiding if necessary, combine the catalytically active metals into the refractory oxide support. In order to obtain a catalyst with particularly good catalytic activity, the method can be carried out through the following stages: (a) impregnating the carrier with one or more solutions containing a noble gold compound selected from the group consisting of platinum, palladium and iridium, and one or more solutions containing a tritium compound, if necessary, having Intermediate drying and / or smoldering; and (b) drying and simmering the impregnated carrier at a temperature within the range of 2 to 6 thieves. A preferred method of impregnating the carrier is a so-called pore volume method It includes treating a carrier with an impregnating solution in the volume of the seed type, wherein the size of the impregnating solution is -11. The paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm (please first Read the notes on the back- ,.

In this way, the complete use of the impregnation solution is achieved. It has been found that this impregnation method is particularly suitable because the resulting catalyst exhibits particularly good performance. For the purposes of the present invention, the impregnation stage (a) may be performed using one impregnation solution containing all metal components or may be performed in two separate impregnation stages for use with platinum and / or palladium and / or grades One stage of impregnation and one stage for impregnation with manganese and / or rhenium may have an intermediate drying and / or scorch stage. The metal compounds which can be used in the impregnating solution for preparing the catalyst according to the invention are known in the art. Typical manganese compounds are salts such as manganese sulfate, manganese nitrate, and manganese acetate that are soluble in water. Typical baht compounds are pergallic acid, ammonium perchain, and potassium perbaate. Typical palladium compounds used in impregnation solutions are tetragas palladium acid (H2PdCl4), palladium nitrate, vaporized palladium (II) and amine complexes thereof. H2PdCl4t is preferred. Typical platinum compounds used in an impregnating solution are hexamethylene acid (H2PtCl6), transammonium hydroxide, and suitable amine amine complexes in the presence of hydrogen acid as needed. In the catalyst preparation, the catalyst is burned in the air in the final stage, so that the metal becomes the form of their oxides, which is a common example. In order to at least partially convert the metals into their sulfides, the catalyst may be presulfided after the final calcination stage and before contact with the feed. Suitable presulfidation methods are known in the art, such as, for example, from European Patent Application Announcement No. 0,181,254; 〇, 329,499; 〇, 448,435 and 〇, 564,317 and International Patent Application Announcement World Intellectual Property Organization Patent No. 93/02793 and World Intellectual Property Organization Patent No. 94/25157. -12- The size of this paper is applicable to the Chinese National Standard (CNS) A4 (2 丨 〇χ297) ¾1T ------. ^ (Please read the precautions on the back first, then this tile) Central Bureau of Standards, Ministry of Economic Affairs Printed by employees' consumer cooperatives A7 B7 V. Description of invention (ίο) Therefore, in another embodiment of the present invention, the method for preparing a catalyst includes the following additional stages: (c) The dried and calcined catalyst is subjected to A pre-curing treatment. In addition to the pre-vulcanization methods described above, pre-vulcanization can also occur through on-site pre-vulcanization. This includes contacting a calcined catalyst with a sulfur-containing hydrocarbon feed under suitable conditions, generally under conditions that are less severe than those applied during the intended operation. The catalyst according to the invention can be regenerated via methods known in the art. A typical method for recovering catalytically active metals from a spent catalyst involves removing the activated catalyst from the reactor, washing the catalyst to remove hydrocarbons', burning off coke and subsequently recovering precious metals and manganese and / or plutonium. The invention is illustrated by the following examples, but the invention is not limited by these specific embodiments. Example 1 A composition consisting of 80% by weight of aluminized zeolite Y (unit cell size of 24.25 Angstroms and silica / alumina mole ratio of 80) and 20% by weight of an oxide binder An acidic carrier. A sample of this carrier is impregnated with a perbasic acid (HReO 0 aqueous solution to reach 20% by weight Re02 (corresponding to 17.1% by weight iRe; the weight percentage is based on the weight of the support) 3 and then a partially prepared catalyst Drying and simmering at 400 ° C for 2 hours, followed by impregnation with an aqueous solution of H2PdCl4 to reach a PdO content of 5% by weight (corresponding to 4.3% by weight of Pd). Finally, air was used at 350 eC. The finished catalyst for intermediate drying and sintering took 2 hours, and the catalyst is also called PdRe / Y. -13- This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) I ------ -赛 ------ ΐτ ------ ^ (Please read and read the notes on the back 孑 4 write this page} d64687 A7 ---------- B7 V. Description of the invention ( 11) Example 2_ A bed consisting of pdRe / Y of more than 20 cm3 mixed with 80 cm3 of cracked silicon particles (SiC 'diameter 0.21 mm) was placed in a reactor. I obtained a PdRe / Y bed It is prevulcanized according to the method disclosed in European Patent-A-〇, 181,254. This method includes a method for diluting n-heptane. The polysulfide was immersed in the second and third nonyl groups, and then dried at 15 (rC under atmospheric pressure of nitrogen for 2 hours. The catalyst was then assisted by hydrogen at a gas rate of 500 N (N1) / kg. The reactor was activated by reaching a total pressure of bar. Within 2 hours, the temperature was increased from the ambient temperature to 25 ° C. Then the feed was introduced and the temperature was increased from 10 ° C / hour to 250T: the temperature was increased to 3 1 °. ° C. Maintained a temperature of 310 ° C for 100 hours. After the Yuancheng activation procedure, it will have the characteristics as shown in Table I (Bp is the boiling point 'IBP and FBP mean the initial and final boiling points respectively).

It can be seen from Table II that the cracking of the feed ingredients to a low boiling point system is minimized, and at the same time the PdRe / Y catalyst has excellent hydrodesulfurization and hydrodenitrogenation activity : Sulfur content and nitrogen content have been reduced by 96.2% and 96.8%, respectively. Table II also shows that the aromatic hydrocarbon conversion system is very good. In this regard, it should be kept in mind that the conversion of polynuclear (three and above) aromatic hydrocarbons and dinuclear aromatic hydrocarbons initially increases the content of mononuclear aromatic hydrocarbons. Conversion rate (expressed by weight%) can be calculated by assuming that aromatic hydrocarbons are hydrogenated by a continuous reaction pathway, that is, assuming _____ -15- This paper is suitable for Laijia County (CNS) ~ Secret (2lQ > < 297 public directors) * / 16 4 68 V. Description of the invention (13) A7 B7 ------ Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs = Conversion of nuclear aromatic hydrocarbons to dinuclear aromatic hydrocarbons, conversion of dinuclear aromatic hydrocarbons It becomes a mononuclear aromatic hydrocarbon and a mononuclear aromatic hydrocarbon is converted into a naphthenic hydrocarbon. Since it is known that when the number of aromatic rings in a multi-core structure decreases, the hydrogenation of an aromatic ring containing I in a multi-core structure usually becomes less kinetically, so this is a correct False [Therefore, the mononuclear aromatic smoke found in the product can come from three sources: (i) from unconverted dinuclear aromatic hydrocarbons present in the feed '(ii) from the raw materials already present in the feed The converted dinuclear aromatic hydrocarbons and (iii) are from the converted dinuclear aromatic hydrocarbons, which, in turn, are from the converted polynuclear aromatic hydrocarbons present in the feed. Based on the continuous pathway mechanism, it was found that the conversion degrees of polynuclear aromatic hydrocarbons, dinuclear aromatic hydrocarbons, and mononuclear aromatic hydrocarbons were as high as 85.3%, 91 3%, and 54 1%, respectively.
